BABY-JUM PER.

SPECIFICATION forming part of Letters Patent No. 230,707, dated August3, 1880.

Application filed April 26, 1880. (No model.) I

To all whom it may concern:

Be it known that I, CHARLES H. LAND, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Baby-Jumpers, and I doherebydeclare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the artto whichit appertains to make and use the same, reference being had to theaccompanyingdrawings,

and to letters or figures of reference marked thereon, which form a partof this specification. Y

Figure 1 of the drawings is a side View, showing the crib in full anddotted lines. Fig. 2 is a perspective view of the crib. Fig. 3 is aperspective view of the railing-clamp. Fig. 4 is a perspective View ofthe jumper, showing the child teetering. Fig. 5 is another perspectiveview, showing the child at rest. Fig.

6 is a side view, showing the jumper in an elevated position. Fig. 7 isa side view, showing some modifications.

This invention relates to the class of baby jumpers for amusing childrenand affording means for the child to rest or sleep in, and is designedas an improvement upon those now in general use in the followingparticulars:

great durability, simplicity, cheapness, noiselessness, freedom fromfriction, and dispensing with the use of metal springs and oiling.

My improvements therefore consist in a spring-board babyjumper composed,essentially, of two parts, to wit: a base-board and a spring-boardsuitably connected at one end with a wedge-shaped block.

It also consists in the combination of the base-board, spring-board, anda crib, or its equivalent,capable of a sliding motion upon thespring-board, to permit the child to thrust its legs through two holesin the bottom of the crib provided for the purpose, whereby the childcan teeter.

It also consists, in combination with the base-board, spring-board, andcrib, or its equivalent, of pivoted supports for sustaining the jumperin an inclined position, so that the child canlook out of the window ofthe house, when placed within a room, and see objects without, as willbe hereinafter more fully set to gain an acute angle, by beveling theparts together, and by introducing at the rear of contact a wedge-shapedblock, I), affording a better support, substantially as shown in Fig. 1of the drawings.

To the end of the spring-board is arranged the crib D, capable of asliding motion, its limit being controlled or regulated by the stops orprojections d on the under side of the springboard, The bottom board ofthis crib is recessed of a depth to correspond with the thickness of thespring-board, and is, also provided with two transverse bars, 0 0,having suitable set means (not shown) for retaining and securing thecrib upon the spring-board'in the desired position.

The sliding crib is constructed as shown in the drawings, Figs. 1 and 2,with a number of vertical bars, f, attached to the bottom board andupper railing, E, which forms a shield or guard to prevent the childfrom falling out. The corner connections of the upper rail, E, arefirmly secured by means of the metallic clamp G, as fully showninperspective inFi'g. 3.

The ends it of the clamp G are passed down the sides of the railing andbent under, so as to lie flat upon the undersurface of the railing.

The bottom board of the crib or basket D is formed with two oblongopenings, H, to permit the child, when of proper age or size, to passits legs or lower limbs through them to teeter or jump itself from thebase-board.

When the child becomes tired of jumping or teetering the legs arewithdrawn from the openings and the sliding crib drawn back to itsnormal position, closing the openings when the child can lie back on apillow arranged within the crib or basket, substantially as shown inFig. 5 of the drawings.

When the child is very young, not able to teeter himself, thespring-board will be operated by the foot of the attendant.

In operation, the weight of the child in the crib will cause the forwardend of the jumper to slightly rise, as seen in Fig. 4, from the floor tothe distance of about one inch, and by depressing this portion of thejumper with the foot, as seen in Fig. 5, which is merely the raising ofthe forward portion of the foot, it causes an undulatory movement at therear end of about six inches, thereby producing upon the infant or childa most agreeable and soothing effect.

It will be observed that the base and spring boards in my jumper aremade of flat pieces of wood, and that the spring-board, being arrangedat an acute angle, aftbrds an incline plane for the child to ascend, andalso a means for the child to enter the crib.

By this arrangement of the spring-board and basket or crib with thebase-board I am enabled to bring the upper end of the springboard withinone i'oot or more from the floor, so that there is no danger of'thechild being injured.

The base-board, near its rear end, is provided with two pivoted supportsor props, I, arranged on opposite sides, (see Fig. 6,) to sustain thejumper with child in an upright orinclined position for furtheramusement. These supports are retained in position from backwarddisplacement by means of a cross-bar, K, attached to the under surfaceof the base-board in such a manner as to be switched in the direction ofthe length of the board.

By means of these supports I am enabled to further amuse the child byadjusting and supporting thejumper on its front end, so that it can beraised up to a window to see objects without.

In Figs. 6 and 7 of the drawings 1 have shown a modification in theconstruction of the crib, also in connecting the forward ends of thebase-board and spring-board by means of a metallic angular piece, M.

The rear ends of the base and spring boards are provided with a catchand hook for com pressing the parts at this end within a small compass,so that the jumper can be stowed awayin the corner of a closet or underthe bed or hung upon the wall.

It will be readily seen that a baby-jumper of this construction is verysimple and noiseless, also free from friction, and needs no oilin g1What I claim as my invention, and desire to secure by LettersPatent,.is-

l. A spring-board baby-juniper consisting of a base-board and aspring-board united directly together at their front ends at an acuteangle, and supported by a wedge-shaped block, substantially asdescribed.

2. The combination, substantially as described, ot' a base-board, aspring-board, and a sliding crib having two openings for the passage ofthe childs lower limbs, the crib being adapted to slide forward upon thespringboard to close the openings and form a crib for the child to liein.

3. The combination, with a base-board, a spring-board, and a crib, ofpivoted supports or props for sustaining the jumper in an upright orinclined position, substantially as described.

4. The combination, with a baseboard, a spring-board, and a crib, ofpivoted supports or props and a cross-bar attached in rear of thepivoted supports, substantially as and for the purpose set forth.

In testimony whereof I atlix my signature in I presence of twowitnesses.

CHARLES H. LAND.
